Brief Introduction
The Vchung 400Gb/s OSFP DR4 Flat Top transceiver module is designed for use in 400 Gigabit Ethernet links over 500m single mode fiber. The module has 4 independent electrical input/output channels operating up to 106.25Gbps per channel. This transceiver consists of a transmitter/receiver unit, each operating on a set of wavelengths at 1310nm. The transmitter path of the module incorporates a bi-directional PAM4 re-timer ASIC integrated with an EML laser and a 4-channel internal driver. On the receiver path, used 4 photodiodes and a 4-channel TIA array, along with the PAM4 re-timer.

 | Optical transceivers port(LC) For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
